Extract underground risks while keeping costs down! Enhance the safety of land transactions through optimized Phase 1 investigations and document screening in environmental assessments.

In the practice of land sale contracts, the discovery of soil contamination after delivery poses a significant business risk, leading to massive damage claims and long-term legal disputes over contract termination. However, for many companies and landowners, the high costs of surveys have been a major barrier to implementing preemptive risk measures. This explanatory document provides detailed practical know-how on "cost-effective and efficient historical investigations" that can be safely adopted by small and medium-sized enterprises and individual landowners with budget constraints. Geotech, a designated investigation agency under the Soil Contamination Countermeasures Act, has established the optimization of Phase 1 investigations to streamline the process of scrutinizing past public notification documents and land history. By introducing efficient document screening that pinpoint risks from vast amounts of information, it thoroughly eliminates excessive on-site investigations, achieving an overwhelmingly low-cost environmental diagnosis. As a powerful and inexpensive supplement to important matter explanations, it visualizes often-overlooked defect risks before contracts are signed and covers how to incorporate special provisions into the sales contract. This is an essential book for promoting smooth real estate transactions while maintaining social credibility.
